IMPROVEMENT IN GAS COOKING APPARATUS.

Specification forming part of Letters Patent No. 137,865,A datedDecember 15,1874; application tiled October 7, 1874.

To all whom it may concern:

Beit known that we, TnoMAs Pnncocx, ot' Wood Green, in the county ofMiddlesex, England, and JOHN O. PEACOCK, of Finsbury Park Road, in thecounty of Middlesex, England, have invented a new and useful Improvementin Gas Cooking Apparatus; and we do hereby declare that the following isa full, clear, and exact description ot' the same, reference being hadto the accompanying drawing forming a part of this specification, inwhich- Figures l and 2 are sectional, and Fig. 3 a front elevation.

The invention Will rst be fully described, and then pointed out in theclaims.

A represents external casing; B, internal metallic casing; O, packing ofnon-conducting material. The packing need not extend farther than withinsix inches from the bottom of the cooking-cham ber. The gas-jets D arefitted to the door E (such door having internal and external casing)with packing` as the body of the apparatus, and are inclosed in a case,F, open at the top. The space between the outer and inner casings of thedoor for about six inches from the bottom is not packed, and is open toexterior air at the bottom. Through this channel, and through holes G inthe internal casing of the door, the air to support combustion isconveyed to the gas-jets D, and the heated products circulate all roundthe oven, and finally make their exit, cooling as they descend throughholes H into the liuc I to chimney J. The back of the apparatus isformed with a double casing, with intermediate space I, forming theflue. The

gas to the jets is conveyed by a suitable pipe; but we prefer to t toour apparatus an arrangement of pipes, K. The pipe K is for the inlet ofgas, the outlets being fitted with taps K. The fresh air may travel tothe burners through a space formed between a true and false bottom ofthe oven, and, after circulating through the oven, pass out through anopening left under the door of the apparatus. We may also dispense withthe covering F for the gas-Haine, and allow the heated products ot'combustion to pass out at bottom ot' ove-n, thence into a box or chamberup to the discharge-line. We may also form, under the bottom ot' oven, aspace in which plates may be warmed.

Having thus described our invention, what We claim as new is- 1. Thecombination, on the inside of cooking' apparatus, with the burner D,ofthe case F, open at top and connected with an air-inlet at the bottom,as and for the purpose described.

2. The combination, with burner-case F, to discharge hot air into theupper part of' chamber, of the discharge-Hue I, having the bottomaperture H to receive the air, the heat of which has been abstracted, asset forth.

The above specification signed by ns this 30th day of April, 1874.
